PSOC™ 4000T – Multi-Sense MCU The world’s best capacitive sensing solution with ultra-low power and best in class signal-to-noise ratio
Best in class low-power capacitive sensing solution with unsurpassed signal-to-noise ratio, liquid tolerance, and multi-sense capabilities coupled with industry leading reliability and robustness.
PSOC™ 4000T microcontrollers extend the PSOC™ 4 product family of Arm® Cortex®-M0+ based microcontrollers with advanced HMI capabilities. PSOC™ 4000T is equipped with Multi-Sense, a comprehensive sensing solution that integrates Infineon's 5th Generation CAPSENSE, inductive sensing, and liquid level sensing.
Infineon’s 5th Generation CAPSENSE™ technology provides 10x higher SNR (signal-to-noise ratio) performance with 10x lower consumption than previous generations of CAPSENSE™.
The PSOC™ 4000T inductive sensing is based on differential and ratio-metric sensing architecture, providing wide flexibility on both sensor inductance and sensor operating frequency.
The PSOC™ 4000T microcontrollers' liquid level sensing technology eliminates the need for contact with the liquid, works in noisy environments, and can detect different liquids and reject foam and residue.
The PSOC™ 4000T family provides an easy upgrade path for PSOC™ 4000 and PSOC™ 4000S based designs to utilize the advanced 5th generation CAPSENSE™ via software and package compatibility. PSOC™ 4000T series enables a variety of applications including wearables, hearables, home appliances, small kitchen appliances, coffee machines and others.
